I bought this product 4 months ago and recently It stop working. Its data transfer speed is also very less 150kb/sec or some time it goes to an mb/sec. it worked well for some days and then started to get disconnected as soon as I connect it to my laptop. Absolutely a poor product. Don’t purchase Lenovo drives. Life of the Drive is not more than half year as per its behavior. I cannot detect it on USB 3.0 port properly. Went to Lenovo service centers but they told me they only deal with computers and I should talk to customer care.
